RESUMO
Retrorectal cystic hamartomas (tailgut cysts) are rare congenital lesions thought to arise from remnants of the embryonic postanal gut. They predominantly occur as asymptomatic retrorectal multicystic masses in women. The treatment of choice is by complete surgical excision. The most important complications of these cysts are infection with a secondary fistula and malignant degeneration. The differential diagnosis includes a wide variety of conditions that occur in the retrorectal space. In this article, 3 cases showing different surgical technical aspects of treatment are presented. In addition, the aetiopathogenic features and histopathological appearance, clinical presentation and complications, imaging features and differential diagnosis of tailgut cysts are described.

Los hamartomas quísticos retrorrectales (tailgut cysts) son tumores congénitos poco frecuentes derivados de remanentes embrionarios postanales del intestino. La mayoría de los hamartomas quísticos son multiquísticos y aparecen como masas asintomáticas en mujeres de mediana edad. El tratamiento de elección es la extirpación completa. Las complicaciones más frecuentes son la infección y el desarrollo de fístulas cutáneas y la degeneración maligna. El diagnóstico diferencial incluye una extensa variedad de patologías que pueden existir en el espacio retrorrectal. En este artículo presentamos 3 pacientes con hamartomas quísticos y realizamos una revisión de su etiopatogenia, las manifestaciones clínicas, las técnicas de diagnóstico, sus complicaciones y los diagnósticos diferenciales. Asimismo, se discuten las diferentes técnicas quirúrgicas posibles para su abordaje quirúrgico (AU)
